Taipei - A spokesman for Taiwan President Ma Ying-jeou said Friday that nothing from the current government had been stolen and leaked to China by an employee in the presidential office.

Prosecutors detained Wang Jen-ping and former parliament aide Chen Pin-jen early Thursday following questioning over their alleged roles in selling state secrets to China.

"As far as we know, the allegations happened before the handover of power to President Ma, not after he took office on May 20," said spokesman Wang Yu-chi.

His comment came after local media reports suggesting confidential information allegedly leaked included Ma's inaugural speech.

"It was not true because the speech was prepared by (close aides) of President Ma and there was no way the (employee) could gain access to it," the spokesman said.

Ma took over from Chen Shui-bian of the pro-independence Democratic Progressive Party as president after Chen completed two four-year terms on May 20 as the island's leader between 2000 and 2008.

Citing prosecution authorities, the spokesman said Wang Jen-ping used to work in the office of the deputy secretary-general to the president, and allegedly leaked confidential information during Chen's tenure.

He said after Ma took office, the suspect was transferred to another office which has no access to key national secrets.

Taipei District Prosecutor Lin Ching-chuan said Friday that investigators had followed the two suspects for six months before arresting them.

He said a search of their homes Wednesday produced more than 100 documents related to defense, diplomacy and Taiwan's policy towards China.

Initial investigations showed Wang photocopied documents and gave them to Chen, who emailed them to Tang Gang, a member of China's Ministry of National Security, Taiwan news reports said.

The reports also said Chen Ping-jen was allegedly forced to spy for the mainland after Chinese intelligence authorities threatened to expose his extramarital affairs with a woman in China. Prosecutor Lin declined to comment. (dpa)
